Abstract: Numerical simulation using finite element (FE) software (DEFORM) was performed for creep-feed grinding of Inconel (IN718) with a 60-grit 150 mm diameter electroplated CBN wheel to predict the normal and tangential force distributions in the grinding zone. The objective was to obtain the force distributions for predicting the maximum forces acting on individual grains and to explore the feasibility to simulate grinding processes with multiple cutting grains. The workpiece and wheel geometries were modelled first using 3D CAD modeller and then imported to DEFORM for simulation. Random distributions of the heights and spatial positions of abrasive grains on the wheel surface were considered in the wheel model. Material properties from material constitutive equations established by conventional cutting tests were used in the simulation. The simulated nodal forces were further processed to obtain the grinding zone force distributions. The simulated results were found to be in good agreement with experimental results.
